Introduce – First generation single crystal superalloy for production with limited use in military and commercial engine blades – Alloy without Re addition * Single crystal superalloys Superalloy developed to minimize grain boundaries to increase creep resistance and temperature acceptance Grain boundary formation is suppressed by suppressing the addition of elements such as C, B, Zr, and Hf, which are grain boundary strengthening elements, and heat treatment at higher temperatures is possible to increase the fraction of γ′ phase and improve microstructure uniform...
